Hi everyone.

I try to retrieve some blob images from my server side using JRDC2. Not many just 18000...
The problem is that every time I try I get time out error.. if i filter my records for example top 100 then everything working fine.
Any idea how I can skip this time out error?

The code I use in B4A is

B4X:
Sub ESFIItemBlob_ReplaseInto(Dt1 As String, FStart As Boolean) As ResumableSub
    Dim AllDone As Boolean
    Dim i As Int = 1
    Dim req As DBRequestManager = CreateRequest
    Dim cmd As DBCommand = CreateCommand("Select_ESitemBlob_ReplaseInto", Array(Dt1, Dt1))
    Wait For (req.ExecuteQuery(cmd, 0, Null)) JobDone(j As HttpJob)
    If j.Success Then
        req.HandleJobAsync(j, "req")
        Wait For (req) req_Result(res As DBResult)
        'work with result
        'req.PrintTable(res)
        For Each row() As Object In res.Rows
            Dim b() As Byte = row(res.Columns.Get("TS"))
            Dim bc As ByteConverter
'            Log(bc.HexFromBytes(b))
            Starter.LocalSQL.ExecNonQuery2($"REPLACE INTO LOCAL_Blob (Item_Code, IItem_GID, BlobData, BlobSize, TS)
            VALUES (?, ?, ?, ?, ?)"$, Array As Object(row(1), row(2), row(3), row(4), bc.HexFromBytes(b)))
        Next
        AllDone = True
    Else
        Log("ERROR: " & j.ErrorMessage)
        AllDone = False
    End If
    j.Release
    Return AllDone
End Sub

The error I get is
ResponseError. Reason: java.net.SocketTimeoutException, Response:
ERROR: java.net.SocketTimeoutException

Any help how to solve it?

I tried your solution @Erel, but now after awhile I get the error

What it means?

Yes, by using ranges in your sql statement and doing it in batches (Maybe 100 at a time)?
